My Car Doesn't Shift?

My Car Doesn't Shift?

Could a system of gears be a sign of the past for the automatic transmission? CVT technology was a new concept a few years ago, but the technology has come a long way over the past decade.  

CVT, it stands for Continuously Variable Transmission, and continuous it is. No gears; no shifting, in-fact the concept has been around for over 500 years.

A Timeline of CVT Innovation

  •         1886 - first toroidal CVT patent filed

  •         1939 - fully automatic transmission based on planetary gear system introduced
  •         1958 - Daf (of The Netherlands) produces a CVT in a car
  •         1989 - Subaru Justy GL is the first U.S.-sold production automobile to offer a CVT
  •         2002 - Saturn Vue with a CVT debuts; first Saturn to offer CVT technology
